APPARATUS FOR CUTTING FABRIC INTO BIAS-WOVEN LENGTHS.

SPECIFICATION forming part of Letters PatentrNO. 676,585, dated June 18, 1901.

Application filed September 11, 1900. Serial No. 29,718. (No model.)

To all whom t may concern:

Beit known that I, FRANK NEWELL, a resident of Leonia, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Cutting Fabric into Bias-Woven Lengths; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved apparatus for cutting cloth into bias-woven lengths, the object of the invention being to provide an improved apparatus of this character which will automatically feed and cut oylindrically-woven knit or braided cloth or fabric in such manner as to produce a continuous or unpieced strip or length of cloth or fabric having bias weave, the length of which is only limited by the length of the cylindrical cloth or fabric.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a planyiew illustrating my improvements. Fig. 2 is an enlarged view illustrating the cloth spreading and feeding mechanism, and Figs. 3 and 4 are enlarged det-ail views of the cutters and their supporting mechanism.

l represents a frame in which a spool 2 is mounted to rotate and on which cylindricallywoven cloth or fabric is wound, which latter when unwound from the spool is passed be= neath a roller 3 in frame 1, so as to cause the cloth to feed always in the plane of the axis of spool 2. The frame 1 is provided with a rearwardlyextending shaft 4, revolubly Vmounted in a standard 5, and a gear-wheel 6 is secured on said shaft and connected by a gear-wheel 6u with a gear-wheel 7 on the drive-shaft 8, so as to revolve the frame 1 and spool carried thereby at a predetermined rate of speed for a purpose hereinafter described.

A spreader 9 is disposed in front of spool 2 and is secured on a shaft 10, which latter is connected by gears 11 12,-shaft 13, and gear 14, with gear 15von the drive-shaft 8 to revolve the spreader at the saine rate of speed as the frame r1, carrying the spool 2. The spreader 9 is a hollow metallic octagonal prism tapering to a cylinder` with the same perimeter as the prism.

drical fabric to be cut. A ring 16 of considerably larger diameter than the spreader at its widest part surrounds the same and is supported and secured against rotation by rods 17, securing the same to the base-plate 1S of the apparatus, and said ring 16 is provided internally with gear-teeth 19, as shown. A second ring 2O of less diameter than ring 16 and of greater diameter than the spreader 9 surrounds the latter and is partially inclosed in the former', the forward end of ring 20, however, projecting beyond the 'ring 16 and made with external gear-teeth 21, connected by idle gear 22 with a gear 23 on drive-shaft 8 of same size as the diameter of ring 20, so.

as to revolve the ring 20 at the ,proper rate of speed. An octagonal frame 24E surrounds the octagonal face of the spreader and is connected at the angles of the octagonal frame to the ring 2O by rods 25, said frame 24 comprising a series of shafts on which are mounted rollers 26, adapted to hold the cloth against the spreader and feed it forward, as will now be explained. A beveled gear 27 is secured on one end of each roller 26 and meshes With bevel-gears 28 on sleeves 29, revolubly supported on rods 25. Gears 30 are also Vsecured on sleeves 29 and mesh with gears 31, supported in brackets 32 on ring 2O vand in mesh with the internal gear-teeth on ring 16. Hence it will be seen that when ring The size of the prism is determined by the diameter of the cylinthe latter is revolved by the mechanism heretofore explained. A frame 33, mounted at an angle to the line of movement of the cloth, is disposed in front' of the spreader and has mounted thereon disk cutters 3l, secured on shafts 35, located one above the other and held between rollers 36. The disk cutters 34 are sharpened on their periphery and overlap each other, so that when said cutters are revolved by belts 37, passed over idle pulleys 38 and connecting pulleys on shafts 35 with a pulley on main drive-shaft 8, they will cut the cloth or fabric diagonally, or, in other words, spirally, and a reel 3S) is located at one side of the cutters 3lC and operated by pulley and belt 4l to Wind the strip of bias fabric thereon as it is cut by the cutters.

The operation of my improvements is as follows: Cloth or fabric which is previously Woven into cylindrical or tubular form is Wound on the spool 2 and the end of the tubular fabric passed beneath roller 3 and onto spreader 9. The frame l and spreader are then revolved by the mechanism heretofore described, and the rollers 26 will engage the fabric and feed it forward simultaneously with its revolution to the cutters 34 to out the same diagonally or spirally, the rollers 36 serving to hold the fabric taut While being cut and feeding the cut strip to the reel 39, on Which it winds. It will thus be seen that as the threads comprising the Weave of the tubular or cylindrical fabric run longitudinally and transversely when the tubular cloth is cut spirally a single length will be cut having the threads at an angle or diagonally,

or, in other Words, the weave Will be bias.

"Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention,

and hence I would have it understood that I do not Wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall Within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In apparatus for producing fabric having bias Weave, the combination of means for feeding a tube of fabric forwardlyand simultaneously rotating it and means for reducing said tube to a single sheet of fabric having bias Weave.

2. In an apparatusfor producing fabric having bias Weave, the combination of a diagonally-disposed cutter, and means for feeding the end of a tube of fabric to said cutter and simultaneously rotating said tube.

3. In an apparatus for producing fabric having bias weave, the combination of diagonally-disposed cutters, means for presenting the end of a tube of fabric between said cutters, means for rotating the tube and means for feeding the tube, whereby-the tube will be reduced to a single sheet having bias Weave.

4. In apparatus for producing fabrichaving bias weave, the combination with diagonallydisposed cuttersfof means for continuously feeding a fabric tube of indefinite length to said cutters and means for rotating said tube while it is being fed forward and cut, to reduce said tube to a sheet of fabric having bias weave.

5. In an apparatus for producing bias fabric, the combination of diagonally-disposed cutters, means for feeding a tube of fabric to said cutters and simultaneously rotating it, and means for receiving and rolling the single sheet of bias fabric thus-produced.

6. In an apparatus for cutting a strip of bias fabric, the combination'of a spreader adapted to hold a cylinder of cloth extended, rollers adapted to feed the cloth lengthwise, means adapted to revolve the spreader, rollers and cloth and a cutter adapted to cut the cylindrical cloth spirally.
